Product Characteristics of Polyester Film

Polyester film is a new type of film material with high comprehensive performance and has excellent functional properties. At present, it has been widely used in various major fields, and plays a very important role in our life, so it is well received and favored by people. So what are the characteristics of polyester film? Let’s get to know it.

Polyester film is characterized by high mechanical strength, good rigidity, strong toughness, excellent electrical insulation, transparent and glossy, non-toxic, odorless, tasteless, wearable, folding resistant, pinhole resistant and tear resistant. The tensile strength is 3 times as high as that of PC film and nylon film, and the impact strength is 3-5 times of that of BOPP film.

Polyester Film

Polyester film has good heat resistance. It can be vacuum coated aluminum and coated with functional coating on the surface, so as to improve its thermal sealing, barrier property, printing performance and some unique optical properties. Polyester film also has excellent cooking resistance, low temperature freezing resistance, good oil resistance and chemical resistance. Except for nitrobenzene, chloroform and benzyl alcohol, most chemicals can not dissolve it.

In addition, polyester film also has other types of packaging film incomparable gas barrier performance, can effectively prolong the storage period of the package. Polyester film is widely used in packaging materials, magnetic recording, photosensitive materials, electronics, electrical insulation, industrial membranes, decoration and other fields because of its excellent physical and chemical properties. It has the characteristics of recyclability and continuous modification.
